DiscordJS机器人启动时获取所有服务器列表及邀请链接需求

Got it, let's get this sorted for you! Your current code only targets a single server (and you don't even know the ID anyway), so we need to adjust it to loop through all the guilds your bot is in instead. Here's how to do it properly, with attention to Discord.js version differences, permissions, and error handling:

核心思路 #

You don't need to know individual server IDs—we can directly iterate through all guilds your bot is part of, then generate an invite link for each (as long as the bot has the right permissions).

Discord.js v14+ (Latest Stable Version) #

Starting with v14, Discord requires invites to be tied to a specific channel. We'll look for the first valid text/voice channel the bot can create invites for:

// Put this inside your client's ready event
client.on('ready', async () => {
  console.log(`Logged in as ${client.user.tag}!`);
  console.log('I am in the following servers:');

  // Loop through every guild the bot is in
  for (const guild of client.guilds.cache.values()) {
    try {
      // Find the first channel the bot can create an invite for
      const channel = guild.channels.cache.find(
        ch => (ch.type === 0 /* Text channel */ || ch.type === 2 /* Voice channel */)
        && ch.permissionsFor(client.user).has('CreateInstantInvite')
      );

      if (!channel) {
        console.log(`${guild.name} - No permission to create invites or no valid channel found`);
        continue;
      }

      // Create a permanent invite (adjust maxAge/maxUses if needed)
      const invite = await channel.createInvite({
        maxAge: 0, // 0 = never expires
        maxUses: 0 // 0 = unlimited uses
      });

      console.log(`${guild.name} - ${invite.url}`);
    } catch (error) {
      console.log(`${guild.name} - Failed to create invite: ${error.message}`);
    }
  }
});

Discord.js v12/v13 #

If you're using an older version, the API syntax for channel types and permissions is slightly different:

client.on('ready', async () => {
  console.log(`Logged in as ${client.user.tag}!`);
  console.log('I am in the following servers:');

  for (const guild of client.guilds.cache.values()) {
    try {
      // Find valid channel for invite creation
      const channel = guild.channels.cache.find(
        ch => (ch.type === 'text' || ch.type === 'voice')
        && ch.permissionsFor(client.user).has('CREATE_INSTANT_INVITE')
      );

      if (!channel) {
        console.log(`${guild.name} - No permission to create invites or no valid channel found`);
        continue;
      }

      const invite = await channel.createInvite({
        maxAge: 0,
        maxUses: 0
      });

      console.log(`${guild.name} - ${invite.url}`);
    } catch (error) {
      console.log(`${guild.name} - Failed to create invite: ${error.message}`);
    }
  }
});

Critical Notes #

• Permissions: Your bot must have the Create Instant Invite permission in a server to generate an invite. If it doesn't, the code will catch the issue and log a message instead of crashing.
• Error Handling: The try/catch blocks prevent your bot from crashing if something goes wrong (like a server blocking invite creation, or network issues).
• Invite Settings: Adjust maxAge and maxUses in the invite creation options if you don't want permanent, unlimited invites.
